Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] The present utility model discloses a stamping die for the upper cover of a shielding cover, as Figures 1-5 shown, which includes a die body 2 provided on the top surface of a driving block 1. One side inside the driving block 1 is movably installed with a threaded rod 902, and the other side inside the driving block 1 is fixedly installed with a guiding rod 903. The outer surface of the threaded rod 902 is threadedly connected with two moving blocks 904, and both of the two moving blocks 904 are movably connected with the guiding rod 903. The outer surface of the threaded rod 902 is provided with two sections of opposite threads. When the threaded rod 902 rotates, the two moving blocks 904 can move in opposite directions. One side of the outer surface of the driving block 1 is fixedly installed with a micro motor 901, and the output end of the micro motor 901 is fixedly connected with the threaded rod 902.

[0023] The top surfaces of the two moving blocks 904 are both movably connected with lifting rods 905, and the ends of the two lifting rods 905 far from the moving blocks 904 are jointly movably connected with a lifting block 906. When the two moving blocks 904 approach each other, the two lifting rods 905 can push the lifting block 906 to rise. When the two moving blocks 904 move away from each other, the two lifting rods 905 can drive the lifting block 906 to descend.

[0024] Moreover, one end of the lifting block 906 extending into the mold body 2 is fixedly installed with a stripping plate 107 for ejecting the upper cover of the shielding cover. When the lifting block 906 moves up and down, the stripping plate 107 can be driven to move up and down to eject the stamped upper cover of the shielding cover in the mold body 2 for demolding. A second rack 106 is fixedly installed on one side of the lifting block 906. When the lifting block 906 moves up and down, the second rack 106 can be driven to move up and down.

[0025] One side inside the driving block 1 is movably installed with a first gear 101, and the first gear 101 meshes with the second rack 106. When the second rack 106 moves up and down, the first gear 101 can be driven to rotate.

[0026] One side inside the driving block 1 is movably installed with a second gear 102, and the second gear 102 meshes with the first gear 101. When the first gear 101 rotates, the second gear 102 can be driven to rotate.

[0027] An activity hole 103 is formed in the outer top surface of the driving block 1, and an activity block 104 is movably connected inside the activity hole 103. A first rack 105 is fixedly installed on the bottom surface of the activity block 104, and a stripping sleeve 6 is fixedly installed on the top surface of the activity block 104. The first rack 105 meshes with the second gear 102. When the first gear 101 drives the second gear 102 to rotate, the second gear 102 can push the first rack 105 to move. When the first rack 105 moves, the activity block 104 and the stripping sleeve 6 can be driven to move.

[0028] When the lifting block 906 rises, it drives the second rack 106 and the stripping plate 107 to rise. Through the transmission of the first gear 101 and the second gear 102, the first rack 105 can drive the activity block 104 and the stripping sleeve 6 to move to one side of the mold body 2 to push the lifted upper cover of the shielding cover into the material guiding frame 8.

[0029] A fixing frame 3 is fixedly installed on the top surface of the driving block 1, and a cylinder 4 is fixedly installed on the inner top surface of the fixing frame 3. A punching head 5 is fixedly installed at the output end of the cylinder 4. When the raw material of the upper cover of the shielding cover is placed in the mold body 2 and the cylinder 4 pushes the punching head 5 to descend, the raw material of the upper cover of the shielding cover can be punched.

[0030] A material guiding frame 8 is fixedly installed on one side of the top surface of the driving block 1 close to the mold body 2. The inner bottom surface of the material guiding frame 8 is inclined, and the upper cover of the shielding cover falling into the material guiding frame 8 will slide into the external container.

[0031] A spring 601 is fixedly installed on one side inside the stripping sleeve 6, and one end of the spring 601 is fixedly installed with a connecting plate 603. A stripping block 602 is fixedly installed on one side of the connecting plate 603. Blocking blocks 604 are fixedly installed on both sides of the connecting plate 603.

[0032] On one side of the top surface of the driving block 1, a limiting frame 7 is fixedly installed. Inside the limiting frame 7, two sliding rods 701 are fixedly installed. The outer surfaces of the two sliding rods 701 are jointly movably connected with a baffle plate 703. The baffle plate 703 can move along the two sliding rods 701. An electric push rod 702 is fixedly installed on the inner bottom surface of the limiting frame 7, and the output end of the electric push rod 702 is fixedly connected with the baffle plate 703. The electric push rod 702 can push the baffle plate 703 to lift and lower. When the unloading sleeve 6 moves, the blocking block 604 will contact the baffle plate 703. As the unloading sleeve 6 continues to move, the connecting plate 603 can squeeze the spring 601. At this time, when the electric push rod 702 pushes the baffle plate 703 to descend so that it does not contact the blocking block 604, the squeezed spring 601 can push the connecting plate 603 and the unloading block 602 to move, so as to push the lifted upper cover of the shielding cover into the material guiding frame 8.

[0033] The working principle of the present utility model is as follows: Place the raw material of the upper cover of the shielding cover in the mold body 2. The air cylinder 4 pushes the stamping head 5 to descend, and then the raw material of the upper cover of the shielding cover can be stamped. Then start the micro motor 901 to drive the threaded rod 902 to rotate, so that the two moving blocks 904 approach each other, and the two lifting rods 905 can push the lifting block 906 to rise. When the lifting block 906 rises, it drives the second rack 106 and the unloading plate 107 to rise. Through the transmission of the first gear 101 and the second gear 102, the first rack 105 can drive the movable block 104 and the unloading sleeve 6 to move to one side of the mold body 2. When the unloading sleeve 6 moves, the blocking block 604 will contact the baffle plate 703. As the unloading sleeve 6 continues to move, the connecting plate 603 can squeeze the spring 601. At this time, when the electric push rod 702 pushes the baffle plate 703 to descend so that it does not contact the blocking block 604, the squeezed spring 601 can push the connecting plate 603 and the unloading block 602 to move, so as to push the upper cover of the shielding cover lifted by the unloading plate 107 into the material guiding frame 8.
